Join Neil deGrasse Tyson, comic co-host Chuck Nice, and astrophysicist Janna Levin as they celebrate the life and achievements of Albert Einstein and his impact on the scientific world around us, including the detection of gravitational waves at LIGO.

If light can’t escape from black holes, how can we observe them at all? Find out from astrophysicist Janna Levin, co-host Matt Kirshen, and Shep Doeleman, the MIT astrophysicist leading the Event Horizon Telescope project to study black hole Sgr A* at the center of our galaxy.

What are gravitational waves, and what can they tell us about our universe? In her first outing as StarTalk All-Star host, cosmologist Janna Levin untangles the astrophysics with help from LIGO co-founder Rainer Weiss and comic co-host Matt Kirshen.

It’s time for another episode of Cosmic Queries! Neil deGrasse Tyson welcomes first time comic co-host Godfrey to ask fan-submitted questions about photons and tachyons; Einstein, black holes and multiple universes; comets, aliens, and so much more.
